| Abstract: | Samples of SO 2- 4/TiO 2 and SO 2- 4/ZrO 2, prepared by impregnation method, were characterized using infrared(IR) and X ray photoelectron spectroscopy. The acidvity was determined by TG of NH 3. The experimental results were correlated with the catalytic activity for the alkylation of isobutane with butenes and the acetylation of benzoyl chloride with toluene. It was found that catalytic activity was corresponding relation with the acidity. |
